ALBERT Gr. EDDY AND GEORGEJ. HOBSON, OF MOUNT VERNON, WASHINGTON.

FARM-GATE Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed April 20, 1908. Serial No. 428,211.

To all whom it may concern:

Be it known that we, ALBERT Gr. EDDY and GEORGE J. Henson, citizens of the United States, residing at Mount Vernon, in the county of Skagit and State of i/Vashington,

have invented certain new and useful Improvements in Farm- Gates, of which the following is a specification.

This invention relates to improvements in gates, and the primary object is to provide ofiicient and durable operating means.

The invention also relates to improvements in the details of construction and arrz'ingement of parts, which will be hereinafter described and particularly pointed out .in the claims.

In the drawings: Figure 1 is a perspective view of the improved gate, showing the same in closed position. Fig. 2 is a view in elevation of the gate in open position. Fig.

3 is a detail section on the line 33, Fig. 2.

Fig. 4: is a view similar to Fig. 2, but showing a slight modification.

The numeral 1, indicates a gate of approved construction, including longitudinal panels 2, connected by transverse connecting bars Pivotally connected to the gate at a point near the center and top, as indicated at 5, are two normally inclined rocking levers 66, pivoted at their lower ends at 77, to a mud-sill 8. Between the pivotal points 55, and the inner end bar 3, arepivoted at 9, two additional similarly inclined levers 1010, pivoted at their lower ends 11, to a mud-sill 12. The levers 6 and 10, are disposed parallel to each other, to

uniformly raise the gate during the opening and closing operation.

Adjacent the inner end bars 3, are two posts 1 1, to the upper ends of which are secured under tension coiled springs 15, con nected at their opposite ends to the levers 6-43, at suitablepoints between the pivotal connections 5 and 7.

Secured near the ends of the uppermost panel 2, and spaced slightly therefrom is a track 15. Adjacent the gate is a post 16, at the upper end of which is pivotally mounted an operating lever 17, having at one end a rope 0,1 other convenient means for operating leve1 '17 and directly over the gate is a rope or other connection 18, having secured at its lower end a sheave 19, the roller of which engages the under side of the track 15*.

Assuming the gate to be in closed position across the roadway, as shown in Fig. 1, when the operating lever 17, is pulled, the gate is elevated on the pivotal points 7 and 11, and by reason of its traveling in the arc of a circle, the track slides freely through the sheave. During the time the gate is being raised from its lowermost position until the levers 6 and 10, are vertical, the tension on the springs is being decreased. The springs are so arranged that they are under tension when the gate is in either open or closed position, therefore, when the operating lever 17, is pulled the springs serve to assist in lifting the gate. hen the gate reaches the position shown in dotted lines in Fig. 2, the momentum is quite sufficient to move it past the dead center, when its own weight will cause it to fall into open position as shown in full lines on said figure; As prevlously stated, as soon as the gate commences to fall from its elevated position tension on the springs is increased, which tends to remove the shock on the gate when it strikes the ground. In the meantime the track slides freely through the sheave, andnecting the posts and the normally inclined" levers, said springs being under tension when the gate is in its open or closed position, a track carried by the gate, said track being parallel with the gate, a pivoted operating lever mounted above the plane of the top of the gate, a connection suspended from the operating gate, and a sheave carried by the connection and engaging under the track,

said track moving freely over the sheave zontal position during the opening and clog: when the operating lever is tilted. ing operation, the traek passing freely over 2.
